Real-time notifications of concurrent email thread replies

ABSTRACT

In an embodiment of the present invention, a first message is determined. The first message is associated with two or more users. The two or more users include a sender of the first message and one or more recipients of the first message. In response to determining that a first user of the two or more users is currently generating a second message, which is a response to the first message, it is determined whether a second user of the two or more users of the first message is currently generating a third message, which is a response to the first message. In response to determining that the second user is currently generating the third message, the first user is notified that the second user is currently generating the third message, and the second user is notified that the first user is currently generating the second message.

BACKGROUND OF THE INVENTION

The present invention relates generally to the field of electronic mail, and more particularly to real-time notification of concurrent email composers in a thread.

Electronic mail, or emails, are digital messages that are exchanged between a sender and one or more recipients. Emails are transferred between devices connected over a network, such as the Internet. Email applications, which allow a user to access, compose, and otherwise utilize emails of the user, operate on a client-server model whereby an email is transferred by an email application to a server where they are stored for a recipient. Email thereby provides asynchronous, as opposed to real-time, correspondence between a sender of a message and a recipient of the message.

SUMMARY

Embodiments of the present invention include a method, computer program product, and system for providing real-time communication in electronic message threads. In an embodiment of the present invention, a first message is determined. The first message is associated with two or more users. The two or more users include a sender of the first message and one or more recipients of the first message. Whether a first user of the two or more users of the first message is currently generating a second message is determined. The second message is a response to the first message. In response to determining that a first user of the two or more users is currently generating a second message, it is determined whether a second user of the two or more users of the first message is currently generating a third message. The third message is a response to the first message. In response to determining that the second user is currently generating the third message, the first user is notified that the second user is currently generating the third message and the second user is notified that the first user is currently generating the second message.

DETAILED DESCRIPTION

Embodiments of the present invention recognize that society relies heavily on email communication. Embodiments of the present invention recognize that having multiple recipients of a single email can cause problems for both the sender and the recipients, causing confusion and unnecessary delays in collaboration. Embodiments of the present invention further recognize that such problems result from the asynchronous nature of communicating through email. For example, multiple recipients of the same email cannot know about the intentions of each other recipient to reply to the email, which can cause uncoordinated responses and further confusion and delays.

Embodiments of the present invention provide for real-time notifications to email users in situations involving concurrent replies in a single email thread.

An email thread is a group of emails that includes an original email, all emails sent in reply to the original email (reply emails), and all emails sent in reply to a reply email. In response to a recipient opening an email that is part of an email thread, the email application of the recipient typically displays the whole email thread (i.e., all emails of the email thread).

The present invention will now be described in detail with reference to the Figures. FIG. 1 is a functional block diagram of a computing environment, generally designated 100, in accordance with an embodiment of the present invention. FIG. 1 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Those skilled in the art may make many modifications to the depicted environment without departing from the scope of the invention as recited by the claims.

In an embodiment, distributed data processing environment 100 includes computing device A 110, server device 120, and computing device B 130. Computing device A 110, server device 120, and computing device B 130 are interconnected through network 102. In an embodiment, distributed data processing environment 100 may additionally include any other device connected to network 102.

In an embodiment, network 102 may be a local area network (LAN), a telecommunications network, a wide area network (WAN) such as the Internet, or any combination of the three, and network 102 may include wired, wireless, or fiber optic connections. In an embodiment, network 102 may generally be any combination of connections and protocols that support communications between computing device A 110, server device 120, computing device B 130 and any other computing device connected to network 102, in accordance with embodiments of the present invention.

In an embodiment, computing device A 110 may generally be any electronic device or combination of electronic devices capable of executing computer readable program instructions. In example embodiments, computing device A 110 may be a personal computer, workstation, tablet computer, mobile phone, or personal digital assistant. In an embodiment, computing device A 110 may be a computer system utilizing clustered computers and components (e.g., database server devices or application server devices) that act as a single pool of seamless resources when accessed by elements of distributed data processing environment 100, such as in a cloud computing environment. In an embodiment, computing device A 110 may include components depicted and described with respect to FIG. 3. In an embodiment, computing device B 130 may be substantially similar to computing device A 110 and may include substantially similar components.

In an embodiment, computing device A 110 includes email application A 112. In an alternative embodiment, email application A 112 may be located on another computing device (not shown) connected to network 102. In an embodiment, email application A 112 may generally be a computer program, application, subprogram of a larger program, or combination thereof that provides functions for handling emails and transferring emails between computing device A 110 and server device 120.

In an embodiment, email application A 112 may provide functions for handling and transferring emails such as sending, receiving, retrieving, displaying, composing, responding to (e.g., replying to, forwarding), and deleting emails. In an embodiment, email application A 112 may provide organizational features such as an inbox for received emails as well as folders for displaying various categories of stored emails such as sent emails, drafted emails, deleted emails, and important emails. In an embodiment, email application A 112 may additionally provide functions for organizing a schedule of a user such as a calendar and reminder notifications. In an embodiment, email application A 112 communicates with collaboration program 122 including notifying collaboration program 122 when an email is being composed by a user of email application 112. In an embodiment, email application A 112 may include one or more user interface devices (not shown) to allow a user to utilize email application A 112. In an embodiment, email application B 132 may be substantially similar to email application A 112.

A user interface is the information, such as graphic, text, and sound, a program presents to a user and the control sequences the user employs to control the program. There are many types of user interfaces. For example, the user interface may be a graphical user interface (GUI). A GUI is a type of user interface that allows users to interact with electronic devices, such as a keyboard and mouse, through graphical icons and visual indicators, such as secondary notations, as opposed to text-based interfaces, typed command labels, or text navigation. GUIs were introduced for computers in response to the perceived steep learning curve of command-line interfaces, which required commands to be typed on the keyboard. The actions in GUIs may be performed by a user through direct manipulation of the graphical elements.

In an embodiment, server device 120 may generally be any electronic device or combination of electronic devices capable of executing computer readable program instructions. In example embodiments, server device 120 may be a workstation, personal computer, personal digital assistant, or mobile phone. In an embodiment, server device 120 may be a computer system utilizing clustered computers and components (e.g., database server devices or application server devices) that act as a single pool of seamless resources when accessed by elements of distributed data processing environment 100, such as in a cloud computing environment. In an embodiment, server device 120 may include components depicted and described with respect to FIG. 3.

In an embodiment, server device 120 includes collaboration program 122. In an alternative embodiment, collaboration program 122 may be located on computing device A 110 or computing device B 130. In yet another alternative embodiment, collaboration program 122 may be located on another computing device (not shown) connected to network 102. In an embodiment, collaboration program 122 may generally be a computer program, application, subprogram of a larger program, or combination thereof that provides real-time notifications to concurrent email composers in a common email thread.

In an embodiment, collaboration program 122 accesses and communicates with email application A 112, email application B 132, and thread repository 124 for providing real-time notifications of concurrent responses in an email thread of which users of email application A 112 and email application B 132 are participants. Collaboration program 122 provides functions that include determining a thread, creating a thread identifier, determining and sending status information of a user of a thread, providing privacy options, and providing access to real-time communication tools, in accordance with embodiments of the present invention.

In an embodiment, server device 120 includes thread repository 124. In an alternative embodiment, thread repository 124 may be located on computing device A 110 or computing device B 130. In yet another alternative embodiment, thread repository 124 may be located on another computing device (not shown) connected to network 102. In an embodiment, thread repository 124 may generally be a storage location for identifying information and status information of emails of the users of email application A 112 and email application B 132.

In an embodiment, thread repository 124 contains identifying information of users of email application A 112 and users of email application B 132 and status information regarding email thread activity of users of email application A 112 and users of email application B 132. In an embodiment, identifying information may include message identifiers of each email of the thread (e.g., values of fields such as message-ID, in-reply-to, references, thread-index, thread-topic, etc.) and a user identifier of each user of each email (e.g., the email address of each recipient and the email address of the sender). In an embodiment, status information regarding email thread activity may include whether a user of the thread is currently generating an email in the thread or whether the user is no longer generating the email. Collaboration program 122 may access thread repository 124 to add to, remove, or otherwise update the identifying and status information stored in thread repository 124, in accordance with embodiments of the present invention. For example, collaboration program 122 may publish, in thread repository 124, an indication of the composing status of a thread user, the email address of the thread user, and the message-ID of the email being generated.

In an embodiment, thread repository 124 may be implemented using any non-volatile storage media known in the art. For example, thread repository 124 may be implemented with a tape library, optical library, one or more independent hard disk drives, or multiple hard disk drives in a redundant array of independent disks (RAID). Thread repository 124 may be implemented using any suitable storage architecture known in the art. For example, thread repository 124 may be implemented with a relational database or an object-oriented database.

FIG. 2 is a flowchart of workflow 200 illustrating operational steps for providing real-time notifications of concurrent replies in an email thread. In the illustrated embodiment, the steps of workflow 200 is performed by collaboration program 122. In an alternative embodiment, steps of workflow may be performed by any other computer program, or programs, while working with collaboration program 122. In an embodiment, collaboration program 122 begins performing the steps of workflow 200 in response to receiving an indication to by a user to provide real-time notifications of concurrent replies in an email thread. In an embodiment, a user of computing device A 110 may provide such an indication through the user interface of email application A 112 and a user of computing device B 130 may provide such an indication through the user interface of email application B 132.

Collaboration program 122 determines a thread and creates a thread identifier (step 205). In other words, collaboration program 122 identifies an email thread and creates a thread identifier corresponding to the thread. In an embodiment, collaboration program 122 determines a thread in response to determining that a user of an original delivered email, such as any recipient of the email or the sender of the email, is composing a response email, such as a reply email or a forward email to the original email. For example, an original sender may send an email to two classmates, user A and user B, regarding a school project. User A may begin composing a reply email to be sent to user B and the original sender to suggest a strategy for the project. Collaboration program 122 may determine a thread in response to user A composing the reply email to user B and the original sender. In an embodiment, the response email may include a new recipient that was not a recipient of the original email.

In an embodiment, collaboration program 122 determines that the user (user A) is composing the response email upon receiving an indication from the email client of the user (email application A 112) that the user is currently composing a response email or, in other words, that the email client of the user is currently generating a response email. For example, email application A 112 may send the indication to collaboration program 122 upon user A clicking the “reply” button, through the user interface of email application A 112, to begin generating the reply email to user B and the original sender. In an embodiment, the indication from email application A 112 includes identifying information, which may include message identifiers of the response email (e.g., values of fields such as message-ID, in-reply-to, references, thread-index, thread-topic, etc.) and a user identifier of each user of the response email (e.g., the email address of each recipient (user B and the original sender) and the email address of the sender (user A)).

In an embodiment, collaboration program 122 creates a thread identifier that is unique to the thread and serves as an identifier of the thread for collaboration program 122. In an embodiment, collaboration program 122 creates the identifier based on the identifying information received from email application A 112. In an embodiment, collaboration program 122 maintains and updates the thread identifier in thread repository 124 as the steps of workflow 200 are performed. For example, in an embodiment, collaboration program 122 maintains a list of all past and current users of a thread (i.e., the thread identifier) and updates the list based on the identifying information determined with each generated response email in the thread.

In an embodiment, collaboration program 122 subscribes user A to the thread identifier. As a result, user A may, for example, receive notifications from collaboration program 122 that another thread user is concurrently composing a response email in the thread (discussed in step 215). In an embodiment, collaboration program 122 updates the thread identifier to indicate that user A is generating a response email (a composing status). As a result, another thread user, upon composing another response email to the thread and being subscribed to the thread identifier, may, for example, receive a notification of the composing status of user A.

Collaboration program 122 determines that a user is composing a response in the thread (step 210). In other words, collaboration program 122 determines that a thread user, such as any recipient or sender of any delivered email in the thread, is composing a response email to one or more other thread users or to a new user. For example, user B may begin composing an email to user A and the original sender in reply to the original school project email in order to suggest a project timeline, and collaboration program 122 may determine that user B is composing a response email to be sent to user A and the original sender. In an embodiment, collaboration program 122 determines that user B is composing a response email upon receiving an indication from email application B 132 that user B is currently composing a response email. In an embodiment, in response to determining that user B is composing a response email in the thread, collaboration program 122 subscribes user B to the thread identifier.

Collaboration program 122 notifies other current thread users that the user is composing a response (step 215). In other words, collaboration program 122 notifies any thread users that are currently composing a response email in the thread identifier that another user is composing a response email. For example, collaboration program 122 may notify user A, the other user subscribed to the thread (i.e., the other user currently composing a response email in the thread), that user B is currently composing a response email in the thread. In an embodiment, collaboration program 122 publishes an indication (or notification) to the thread identifier that user B is composing a response email, and email application A 112 receives the indication and notifies user A through the user interface of email application A 112. In an embodiment, collaboration program 122 notifies other current thread users that the response email currently being composed includes a new recipient (i.e., a recipient who was not a recipient of the original email).

In an embodiment, prior to notifying other thread users that a user is currently composing a response, collaboration program 122 provides a privacy option for the composing user to indicate that other thread users, or particular thread users, should not receive a notification of the composing status of the user. For example, upon receiving an indication from email application B 132 that user B is composing a response and prior to publishing the composing status of user B to the thread identifier, collaboration program 122 may provide a privacy option for user B to allow user B to compose the response without notifying user A and without providing an option to user A for real-time communication with user B (discussed subsequently).

In an embodiment, collaboration program 122 provides an option to, or otherwise receives an indication from, the original sender of the original email of the thread (discussed in step 205) to not provide the privacy option to composing users and to always notify other thread users of a composing status of a thread user. For example, in response to receiving an indication from the email client (not shown) of the original sender, collaboration program 122 may provide an option for the original sender to indicate that a privacy option should not be provided to future thread users of a future thread that includes the original school project email.

In an embodiment, collaboration program 122 provides an option for real-time communication with the composing thread user. In other words, in addition to providing the other current thread users subscribed to the thread identifier a notification that a thread user is currently composing a response, collaboration program 122 provides an option to each current thread user to engage in real-time communication with the composing thread user, and collaboration program 122 provides an option to the composing thread user to engage in real-time communication with one or more other current thread users. For example, in response to user B composing a response email while user A is currently subscribed (i.e., also currently composing a response email), collaboration program 122 may provide user A an option to engage in real-time communication with user B through an instant messaging application (not shown), which may allow user A and user B to discuss the strategy and timeline of the school project more efficiently. In an embodiment, real-time communication may include tools for instant messaging, telephone, and A/V meeting (e.g., video messaging).

Collaboration program 122 determines that the user is no longer composing a response in the thread (step 220). In other words, collaboration program 122 determines that the composing thread user is no longer composing a response email to one or more other thread users or to a new user. For example, collaboration program 122 may determine that user B is no longer composing the response email to user A and the original sender. In an embodiment, collaboration program 122 determines that user B is no longer composing a response email upon receiving an indication from email application B 132 that user B is no longer composing a response email. For example, email application B 132 may send such indication to collaboration program 122 that user B is no longer composing the response email upon user B sending the response email to user A or, alternatively, upon user B closing the response email window through the user interface of email application B 132. In an embodiment, in response to determining that user B is no longer composing a response email in the thread, collaboration program 122 removes user B from the thread identifier.

Collaboration program 122 notifies other current users that the user is no longer composing a response (step 225). In other words, collaboration program 122 notifies the other thread users currently composing a response email (i.e., currently subscribed to the thread identifier) that the user is no longer composing a response email. In an embodiment, collaboration program 122 publishes an indication (or notification) to the thread identifier that user B is no longer composing a response email, and email application A 112 receives the indication and notifies user A through the user interface of email application A 112.
